OPERATIONAL SAFETY
WARNING
Operation of electronic equipment involves the use of voltages and currents that
may be dangerous to human life. Note that under certain conditions dangerous
potentials may exist in some circuits when power controls are in the OFF position.
Maintenance personnel should observe all safety regulations.
Do not make any adjustments inside equipment with power ON unless proper
precautions are observed. All internal adjustments should only be made by suitably
qualified personnel. All operational adjustments are available externally without
the need for removing covers or use of extender cards.

openGear® INTRODUCTION
Developed by Ross Video, openGear® is a standard where various manufacturers can design their equipment to fit
a common frame allowing the end user to mix and match the various openGear® cards available in the market
place together in one frame. This allows a single frame to be used instead of multiple different vendor’s frames
that each would otherwise be using their own proprietary standard.
A simple to use monitoring and control software called DashBoard™ is a free program downloadable from the
openGear® website (www.opengear.tv) that allows the user to remotely monitor and control an openGear® type
card fitted within an openGear® frame that meets the openGear® standard for DashBoard™ control. A link is also
supplied via the IRT Electronics website (www.irtelectronics.com) under the openGear® navigation section.
IRT Electronics’ openGear® cards are designed to meet the openGear® standard for mounting within the
openGear® OG3-FR frame and its earlier version DFR-8300 frame, and is fully compliant with DashBoard™ control.
The openGear® frame manual, DashBoard™ control software and information regarding the frame’s power
supplies, controller card and frame accessories are available for download at the openGear® website.
The term openGear® is a registered trade mark of Ross Video Limited.
DashBoard software Control™ is a trade mark of Ross Video Limited.

9-27dB path loss at 3G
(>30dB at HD and SD)
The IRT-6632-DDT and IRT-6632-DDR are dual transmit and receive modules designed principally for use as two
independent serial data fibre optic transmission links for 3G-SDI, HD-SDI or SD-SDI applications conforming to
SMPTE standards 424M, 292M and 259M-C using 9/125 μm single mode fibre. This enables the use of space saving
fibre optic cable for reliable transmission of digital video signals over lengths greater than can be achieved with
coaxial cable.
In addition, the links may be used for ASI transport streams for use with MPEG compressed video streams or other
270 Mb/s type data.
The transmitters feature automatic input cable equalisation and an active loop through monitoring port on each
input.
Both the transmitter and receiver modules are configurable for automatic changeover to both outputs on loss of
either input, if required.
The receivers use APD detectors with signal conditioning and reclocking circuits. The data rates are automatically
set to match the 3G-SDI, HD-SDI or SD-SDI/ASI rates dependent on the actual input data rates to the transmitters.
The transmitter and receiver modules are compatible with IRT’s single channel fibre cards for use as two
independent fibre paths starting from or coming to a single location.
A link selectable “keep link alive” signal is available to maintain optical link operation when no electrical input is
present.
2
Optionally a 1310/1550nm WDM optical combiner can be fitted to allow for combined use on a single fibre.
The IRT-6632-DDT and IRT-6632-DDR are designed to fit the openGear® standard 2RU frames which allow a
mixture of cards from various manufacturers to be mounted within the same frame.
DashBoard™ control software is available as a free download.
Standard features:
• 2 independent fibre links.
• Transports 3G-SDI, HD-SDI, SD-SDI or ASI signal rates.
• Transmitter (Tx) and receiver (Rx) can be used separately with 2 independent single channel
fibre Rx and Tx cards.
• Path lengths up to 30 dB1 optical path loss using 9/125μm single mode fibre.
• Optional on-board WDM2 optical combiner for use on a single common fibre.
• DashBoard™ and SNMP software monitoring and control.
NOTE: 1 27dB path loss at 3G. Typically >30dB at HD and SD. Fitted with APD detector.
2 With WDM option fitted for combined use on a single fibre, optical path loss is reduced by
approximately 2dB.

INSTALLATION
Pre-installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling precautions
should be observed.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Installation in openGear® frame:
See details in separate manual downloadable from the openGear® website (www.opengear.tv).
Signal Connections:
IRT-6632-DDT:
The default settings of the IRT-6632DDT are to automatically operate at either 2.97 Gb/s 3G-SDI, 1.485 Gb/s HD-SDI or
270 Mb/s SD-SDI / ASI signals and do not require any adjustment prior to use, with the exception of DIP switch
options described in the Configuration section of this manual that also allow SD only, HD/SD only or reclocker
bypass modes of operation.
The two transmitter sections of the IRT-6632-DDT act independently from each other in that the signal rates are
both independently set.
The serial digital signal connections are made to the BNC connectors on the rear panel. IN 1 is the input to the Tx1
transmitter and IN 2 is the input to the Tx2 transmitter. With DIP switch SW1-6 OFF, if either of the inputs, IN 1 or
IN 2, are absent or invalid, the valid input will switch in automatically to drive both Tx1 and Tx2 optical outputs.
Upon restoration of a valid signal to the absent/invalid port, the optical transmitter automatically restores back to
the condition of IN 1 feeding Tx1 and IN 2 feeding Tx2. With SW1-6 ON, automatic changeover is disabled and only
the transmitter with the valid signal present will be outputted.
The OUT 1 BNC connector acts as a monitor port for IN 1, whilst the OUT 2 BNC connector acts as a monitor port
for IN 2.
IRT-6632-DDR:
The default settings of the IRT-6632-DDR are to automatically operate at either 2.97 Gb/s 3G-SDI, 1.485 Gb/s HD-SDI
or 270 Mb/s SD-SDI / ASI signals and do not require any adjustment prior to use, with the exception of DIP switch
options described in the Configuration section of this manual that also allow SD only, HD/SD only or reclocker
bypass modes of operation.
The serial digital signal connections are made to the BNC connectors on the rear panel. Two signal outputs, OUT 1
and OUT 2, are provided. OUT 1 is the signal output of receiver Rx1, whilst OUT 2 is the signal output of receiver
Rx2. With DIP switch SW1-6 ON, if either of the optical inputs, Rx 1 or Rx 2, is absent the valid input will switch in
automatically to drive both OUT 1 and OUT 2 signal outputs. Upon restoration of a valid signal to the absent Rx
fibre port, the receiver automatically restores back to the condition of Rx1 feeding OUT 1 and Rx2 feeding OUT 2.
With SW1-6 OFF, automatic changeover is disabled and only the receiver with the valid signal present will be
outputted.
Note that BNC connectors IN 1 and IN 2 are not used.

Revision 00
IRT-6632-DDT & IRT-6632-DDR
Fibre Optic Connections:
Optical connections are made to the panel adapter mounted on a bracket at the rear of the module. Care must be
taken to provide a clean surface on the optical connectors and in inserting the plug of the external fibre to prevent
damage to the alignment ferrule of the panel adapter. Type of fibre used must be single mode type.
The standard configurations for the IRT-6632-DDT and IRT-6632-DDR have separate LC/PC optical connectors for
the two transmitter (Tx1 & Tx2) and receiver (Rx1 & Rx2) sections. The IRT-6632-DDT Tx1 optical output connector
is the upper half of the optical connector, whilst the Tx2 optical output connector is the lower half. Likewise the
IRT-6632-DDR Rx1 input connector is the upper half of the optical connector, whilst the Rx2 optical input
connector is the lower half.
If the IRT-6632-DDT and IRT-6632-DDR are fitted with the optional 1300/1550nm wave division multiplexer (WDM),
only one common SC/PC optical connector is provided with both IRT-6632-DDT Tx1 and Tx2 functions and
IRT-6632-DDR Rx1 and Rx2 functions occurring on a single fibre. When operating the IRT-6632-DDT with the WDM
option fitted, Tx1 is fitted with a 1310nm laser and Tx2 with a 1550nm laser.
Note that for path lengths ≤ 9 dB for APD detectors, or ≤ 3 dB for PIN detectors, an optical attenuator must be
used to avoid over driving the IRT-6632-DDR.

IRT-6632-DDT & IRT-6632-DDR
OPERATION
The IRT-6632-DDT is a dual electrical to optical transmitter with two separate laser drivers on the one card. Each laser
driver is independent in its operation from the other and is fed with its own independent single channel 3G-SDI,
HD-SDI or SD-SDI (or ASI) electrical signal. The standard laser wavelengths are 1310 nm (corresponding to input 1) and
1550 nm (corresponding to input 2), which allow the outputs to be optically multiplexed through a wave division
multiplexer (WDM), if required. Other wavelength combinations are available on request.
Likewise the IRT-6632-DDR is a dual optical to electrical receiver with two separate optical detectors on the one card.
Each optical detector is independent in its operation from the other and outputs its own independent single channel
3G-SDI, HD-SDI or SD-SDI (or ASI) electrical signal. The detector types available are either dual APD (standard) or dual
PIN. The APD detector allows a greater optical path loss, which allows a farther distance optical path, compared to PIN
detectors. However, for optical path lengths less than 9dB for APD detectors, or 3dB for PIN detectors, optical
attenuators are required so as to not overload the detectors, else damage to the detectors themselves may also occur.
Both the IRT-6632-DDT and IRT-6632-DDR are fully operable with previous IRT single channel 3G, HD or SD fibre links.
Two optical LC/PC connectors (standard) are directly connected to the main card via the rear of the unit. The order of
the optical connectors correspond to the same order as the electrical BNC connectors as labelled on the rear
assembly.
Optionally a two channel wave division multiplexer (WDM) can be directly fitted to both the IRT-6632-DDT and
IRT-6632-DDR to allow simultaneous transmission / reception of optical signals on a single fibre.
The default settings of the IRT-6632-DDT and IRT-6632-DDR are set to automatically operate at either 2.97 Gb/s 3GSDI, 1.485 Gb/s HD-SDI or 270 Mb/s SD-SDI (or ASI). However, either DIP switch or DashBoard™/SNMP settings allow
the units to be independently set for SD only, SD/HD only or reclocker bypass modes.
2.97 Gb/s 3G-SDI, 1.485 Gb/s HD-SDI or 270 Mb/s (ASI or SDI) type of signals are connected to two 75 Ω BNC
connectors (IN 1 and IN 2) of the rear assembly of the IRT-6632-DDT fibre optic transmitter. Front edge LEDs
indicates the presence and data rates of valid input signals. OUT 1 and OUT 2 BNC connectors of the IRT-6632-DDT
monitor the respective IN 1 and IN 2 signals.
If one of the inputs is not present or if its rate does not match the preset rate of the channel, the other input, if
valid, can be automatically switched (if enabled) to both the optical outputs. On resumption of a valid signal the
optical transmitters automatically switches back to their respective inputs.
With the data rate set for bypassed mode, the reclocker is bypassed allowing signals other than 3G-SDI, HD-SDI or
SD-SDI to pass through. If the data rate does not match that of 3G-SDI, HD-SDI or SD-SDI all front panel signal data
rate LED’s will flash to indicate that an unknown data rate has been detected. Likewise an ‘unknownPresent’ data
rate is reported via DashBoard™ & SNMP.
If the laser is set for permanent operation, on loss of a valid input signal, a 54MHz oscillator is switched into the
optical output so that the optical receiver still recognizes the optical link as being valid. This 54MHz signal does not
affect the signal reclocking detector circuitry of the receiver, which is used in signal presence / alarm indication on
detection or absence of a valid 3G, HD or SD signal.
Through the use of DashBoard™ or SNMP (see separate sections of this manual) it is possible to remotely monitor
and control various functions not available via the local DIP switch control. Such as, for example, it is possible to
individually disable the channels on either the IRT-6632-DDT and IRT-6632-DDR locking out an end user’s
functionality should this be desired. When a channel has been disabled, should an electrical signal be present, the
corresponding channel LED will flash - not to be confused with situation where the data rate does not match the
set data rate as described above.
The BNC outputs, OUT 1 and OUT 2, of the IRT-6632-DDR receiver are the same signals that were originally
inputted to the opposite IRT-6632-DDT transmitter. Front edge green LEDs indicate the presence of a valid locked
3G-SDI, HD-SDI, or an SD-SDI type of output signal. IN 1 and IN 2 BNC connectors of the IRT-6632-DDR card are not
used.

Front Edge LED Indicators:
If the Tx (or Rx) input signal rate does not match the set rate the
corresponding LED will flash.
In this example the Tx1 section has been set for either HD/SD only or
SD only with its input (IN 1) is being fed with a 3G-SDI source. The 3G
LED of Tx1 will flash indicating that its input is at the 3G-SDI rate. The
input (IN 2) of Tx2 is being fed with an SD-SDI signal as indicated by the
Tx2 SD (SD IN 2) LED being illuminated. In this particular case the SD
LED of Tx1 (SD IN 1) is also being illuminated indicating that the
automatic changeover function is enabled with IN 2 feeding both Tx1
and Tx2 outputs.

IRT-6632-DDR
IRT-6632-DDT
Optical present, optical low, and optical input failures, on the
IRT-6632-DDR are indicated by bi-colour illuminated OPTICAL LEDs. In
this example the OPTICAL LED of Rx 1 is flashing and is illuminated
green, but so is the received SD OUT 1 signal LED illuminated green.
This indicates that an SD signal is being received even though the
OPTICAL alarm LED is illuminated and flashing, thus the OPTICAL alarm
LED of Rx 1 is indicating that the optical signal level is low, or
approaching the minimum signal strength allowed before signal failure
takes place, whence the receiver output will be muted. Note however
that it is still possible for the optical signal strength to be low and still
allow an errored data signal to be received before signal muting takes
place. The optical low trigger point can vary between the plug-in
receivers, so if operating at signal paths close to the recommended
maximum specified threshold, signal analysis should be performed to
check the accuracy of the received signal if the OPTICAL LED is flashing
green.
SD only, HD/SD only modes:
Note that it is possible to set the unit to operate as an SD rate only or HD/SD rate only mode by use of the DIP
switch configuration controls. However in situations where it is desired that the end user does not have control
over the intended setup, it is possible to set the unit to the desired rate via SNMP control and to lock it to SNMP
only control so that the end user cannot override the setup parameters by use of the DIP switches. This is intended
for situations where a link has been leased to a customer who is only paying for a certain data rate path such as SD
only or HD/SD only as opposed to the full 3G rate.

SNMP SOFTWARE CONTROL
Control via SNMP is possible via a third party Network Management System (NMS) provided the openGear® frame
is fitted with a relevant Network Management card. In the case of the OG3-FR frame the MFC-8322-NS network
management card is required for SNMP control. In the case of either the DFR-8310 or DFR-8321 frames either the
MFC-8310-NS or MFC-8320-NS cards are required for SNMP control. Relevant frame MIBs and card MIB required to
interface to NMS software - see IRT Electronics website (www.irtelectronics.com) for MIB download.
The MIB file for the IRT-6632-DDT and IRT-6632-DDR is a common MIB file for the family of IRT-6630 fibre links and
is named IRT-663x-Dxx. Not all parameters in the MIB file relate to these cards.

MAINTENANCE & STORAGE
Maintenance:
No regular maintenance is required.
Care however should be taken to ensure that all connectors are kept clean and free from contamination of any
kind. This is especially important in fibre optic equipment where cleanliness of optical connections is critical to
performance.
Storage:
If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed
plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be
included to deter corrosion.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
WARRANTY & SERVICE
Equipment is covered by a limited warranty period of three years from date of first delivery unless contrary
conditions apply under a particular contract of supply. For situations when “No Fault Found” for repairs, a
minimum charge of 1 hour’s labour, at IRT’s current labour charge rate, will apply, whether the equipment is
within the warranty period or not.
Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on
components shall be extended by IRT only to the extent obtainable from the component supplier.
Equipment return:
Before arranging service, ensure that the fault is in the unit to be serviced and not in associated equipment. If
possible, confirm this by substitution.
Before returning equipment contact should be made with IRT or your local agent to determine whether the
equipment can be serviced in the field or should be returned for repair.
The equipment should be properly packed for return observing antistatic procedures.
The following information should accompany the unit to be returned:
1.
2.
3.
4.
5.
6.
7.
A fault report should be included indicating the nature of the fault
The operating conditions under which the fault initially occurred.
Any additional information, which may be of assistance in fault location and remedy.
A contact name and telephone and fax numbers.
Details of payment method for items not covered by warranty.
Full return address.
For situations when “No Fault Found” for repairs, a minimum charge of 1 hour’s labour will apply,
whether the equipment is within the warranty period or not. Contact IRT for current hourly rate.
Please note that all freight charges are the responsibility of the customer.
The equipment should be returned to the agent who originally supplied the equipment or, where this is not
possible, to IRT directly. Details of IRT’s direct address can be found at IRT Electronics’ website.
